Performance and characteristics of the camera filter

Performance and characteristics of the camera filter.In fact, the performance of different filters is also different. For example, the basic function of color temperature conversion filters and color temperature compensation filters is to change the color temperature of the imaging light. They are manufactured to overcome the limitation that the film itself cannot change the … Read more

How to use the aperture correctly in photography?

How to use the aperture correctly in photography?Aperture, also known as aperture diaphragm, is used to change the aperture size to control the luminous flux of the imaging carrier. In 1939, Frenchman Martin invented the automatic aperture of the camera. The size of the aperture affects the luminous flux. The so-called luminous flux is the … Read more

Camera’s metering mode

Camera’s metering mode.The so-called metering refers to the camera metering system (only continuous light source can be measured), or the process of measuring the reflected light brightness of the subject with a light meter. Metering is a prerequisite for correct exposure. Metering not only determines the tone, but also affects the color tone. Under different … Read more

What is air perspective, form perspective, shadow perspective, and tonal perspective?

What is air perspective, form perspective, shadow perspective, and tonal perspective?Perspective is a visually based spatial relationship based on near-large and far-small. There are two types: physical perspective and air perspective. Perspective phenomenon is far smaller and nearer, so perspective is also called “far and near method”. Perspective was originally a painting term, but now … Read more
